METHOD FOR HYDRODYNAMIC ACOUSTIC SIGNAL GENERATION

摘要

generating acoustic signals in model aqueous liquids simulating liquid fuels for space rocket system engines. SUBSTANCE: liquid jet speed is raised to critical value followed by its deceleration to form closed cavitation area. Prior to raising water speed excess concentration of hydrogen ions or hydroxyl group ions is set up in water jet. Aqueous solution of ampholyte-type surface active agents is injected in water jet and uniformly distributed over its cross-sectional area. Prior to introducing mentioned solution liquid temperature in jet is raised to value higher than Kraft point for given type of surface active agent but not lower than boiling point of liquid in jet. Concentration of surface active agent in jet is maintained to be equal to or higher than critical concentration of micelle formation concentration but lower than coagulation gel structure concentration. EFFECT: enhanced radiation intensity. 3 dwg
